Abstract
There is provided a method for forming an image, which comprises processing a silver halide color photographic material that has a high-silver-chloride silver halide emulsion and which contains in the photographic material a nitrogen-containing heterocyclic compound, the solubility product of which for the silver salt is in a limited range, with a color developer containing chloride ions and bromide ions in a limited concentration, respectively. The method is excellent in forming an image that can be performed rapidly, and is high in sensitivity, in prevention of processing color-mixing, and in less fluctuation of the photographic quality involved in continuous processing.
Claims
exact text as granted — not AI-modifiedWhat we claim is:
1. A method for forming an image, which comprises processing an image-wise exposed silver halide color photographic material comprising a base having thereon at least red-sensitive, blue-sensitive and green-sensitive silver halide emulsion layers each containing at least one corresponding color coupler, and a magenta coupler in the green-sensitive silver halide emulsion layer is a 5-pyrazolone magenta coupler represented by the following formula: ##STR111## wherein R 10 represents an unsubstituted aryl group or a phenyl group having at least one substituent selected from the group consisting of a halogen atom, an alkyl group, an alkoxy group, an alkoxycarbonyl group, an acylamino group, a sulfamido group, a sulfonamido group, and a cyano group, Q represents a coupling split-off group represented by formula (V) below, and R 9 represents an anilino group of the following formula: ##STR112## wherein R 11 represents an alkoxy group having 1 to 30 carbon atoms, an aryloxy group or a halogen atom, and R 12 and R 13 each represents a hydrogen atom, a halogen atom, an alkyl group, an alkoxy group, an acylamino group, a sulfonamido group, a sulfamoyl group, a sulfamido group, a carbamoyl group, a diacylamino group, an aryloxycarbonyl group, an alkoxycarbonyl group, an alkoxysulfonyl group, an aryloxysulfonyl group, an alkanesulfonyl group, an arylenesulfonyl group, an alkylthio group, an arylthio group, an alkoxycarbonylamino group, an alkylureido group, an acyl group, a nitro group, or a carboxyl group; ##STR113## wherein L 1 and L 2 each represent a methylene group or an ethylene group, l and m each are 0 or 1, R 1 represents a hydrogen atom, an alkyl group, an aryl group, or a heterocyclic group, R 2 represents a group bonded to A through a carbon atom, an oxygen atom, a nitrogen atom, or a sulfur atom, A represents a carbon atom or a sulfur atom, n is 1 when A is a carbon atom, or 1 or 2 when A is a sulfur atom, B represents a carbon atom, an oxygen atom, a nitrogen atom, or a sulfur atom, X represents a group of atoms required for forming a ring, R 1 and R 2 may bond together to form a ring, and B and R 2 may bond together to form a ring when B represents a carbon atom or a nitrogen atom, at least said green-sensitive silver halide emulsion layer comprises a high-silver-chloride silver halide emulsion comprising silver halide grains, 95 mol % or more of said grains comprising silver chloride and said grains comprising a localized silver bromide layer, and said green-sensitive silver halide emulsion layer containing an anti-fogging nitrogen-containing heterocyclic compounds elected from the group consisting of mercaptotriazoles and mercaptotetrazoles in an amount of 1×10 -4 to 1×10 -1 mol per mol of silver halide, the solubility product of which for the silver salt is 10 -10 or less but 10 -18 or more, with a color developer containing chloride ions in an amount of 4.0×10 -2 to 1.0-1 mol/l and bromide ions in an amount of 5.0×10 -5 to 5.0×10 -4 mol/l.
2. The method as claimed in claim 1, wherein the high-silver-chloride silver halide emulsion is substantially free from silver iodide.
3. The method as claim 1, wherein the solubility product for the silver salt 10 -10 .5 to 10 -16 .5.
4. The method as claimed in claim 1, wherein the high-silver-chloride silver emulsion comprises grains having a layered-structure.
5. The method as claimed in claim 1, wherein the high-silver-chloride silver halide emulsion comprises grains having a structure with nonlayered parts different in halogen composition, inside the grain or on the surface of the grain.
6. The method as claimed in claim 1, wherein the coating amount of silver of the silver halide color photographic material is 0.90 g/m 2 or less.
7. The method as claimed in claim 1 wherein the silver halide color photographic material contains a cyan coupler selected from the group consisting of phenolcyan couplers and naphthol-cyan couplers.
8. The method as claimed in claim 1, wherein the color developer is substantially free from sulfite ions.
9. The method as claimed in claim 1, wherein the processing time of the color development is in the range of 20 seconds to 5 minutes.
10. The method as claimed in claim 1, wherein said high-silver-chloride silver halide emulsion comprises 98 to 100 mol % of silver chloride.
11. The method as claimed in claim 1, wherein the silver bromide content in the localized layer is at least 10 mol %.
12. The method as claimed in claim 1, wherein each of the red-sensitive and blue-sensitive emulsion layers comprise silver halide grains which comprise 95 mol % or more of silver chloride.
13. The method as claimed in claim 1, wherein the silver halide grains in the green-sensitive silver halide emulsion layer containing said 5-pyrazolone magenta coupler comprise 98 mol % or more of silver chloride.
14. The method as claimed in claim 1, wherein the silver bromide content in the localized layer is at least 10 mol %, and the silver halide grains in the green-sensitive silver halide emulsion layer containing said 5-pyrazolone magenta coupler comprise 98 mol % or more of silver chloride.Cited by (0)
